Pyrometallurgical Process an overview ScienceDirect

The next step is the converting process in the Cu converter by blowing hot air from tuyeres in order to obtain molten Cu matte (Cu–Fe–S) (35%–70% Cu). This step oxidizes iron sulfide and converts copper sulfide to metallic blister Cu (about 98.5% Cu). The last step is

Review of copper pyrometallurgical practice: today and

Abstract. The pyrometallurgical processing of copper varies worldwide with respect to the charge materials, process, operating parameters, and the physical shape, size, and orientation of the vessel. Plant operations may be either batch, semi-continuous, or fully continuous to produce blister copper or other end product.

Industrial grade pyrometallurgy is usually direct put the WPCBs containing 5%–40% copper into the blast furnace, and the product is black copper containing 70%–85% copper. The black copper is then poured into the converter, which makes an oxidizing slag of Pb, Zn, and Sn, and the copper that contains 95% copper

Pyrometallurgy an overview ScienceDirect Topics

The recycling process can be carried out with or without the presence of a reducing agent (usually carbon based). In order to avoid the use of a reducing agent, the total pressure of the system must be about 10 –4 bar to enable the decomposition of CdO at 850–900 °C producing Cd vapour (Espinosa and Tenório, 2004).. If the process is carried out with the aid of a reducing agent, the

Extraction Of Copper Mining, Concentration, Smelting

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper
